The V2 Engineer

Hans Edler worked
with other scientists on the V 2 bomb. No one scientist / engineer can be
blamed for its creation.

The doodlebug:

The forerunner of the V 2, the V 1, was also known as the
doodlebug. These were powered by diesel and only landed when they ran out of
fuel. It sounded like a bus or lorry running down the hill out of control. You
worried when it went quiet; that was when it would fall to the ground and
discharge its bomb. The V2 was more accurate with its targets and was much
quieter.

Some interesting statistics:

The Manhattan (development of the nuclear bomb) project cost
the US $2 billion (27 billion today).

The cost of V 1 and V2 was $20 billion.

Technical details of the V2 :

At launch the A-4 propelled itself for up to 65 seconds on its own power
The fuel and oxidizer pumps were steam turbines, and the steam was produced
by concentrated hydrogen peroxide with potassium permanganatecatalyst. Both
the alcohol and oxygen tanks were an aluminium-magnesium alloy.
The combustion burner reached a temperature of 2500–2700 °C (4500 –
4900 °F). The fuel waspumped into
the main burner chamber through 1,224 nozzles, which assured the correct
mixture of alcohol and oxygen at all times.
The V-2 was guided by four external rudders on the tail fins.
The V2 was the first rocket to be designed that could go into space.
However, it never went up, only horizontally to attack London.

What Hans told Renate:

You know also that I
was involved in war work even before you left Germany so there was no way that
I could leave with you or your mother. If I’d tried to, it may have meant the
two of you would have not been able to get away. Neither could I refuse to work
on the very weapons that were causing havoc in England. I did go a little more
slowly sometimes …. I hope I did not prolong the agony.
